Can we talk about that 30% energy savings claim from the viral HVAC hack article

Kept seeing that post about wrapping your AC filter in a damp cloth to save 30% on cooling. Tried it for three days in my duplex. Filter got moldy fast and the unit froze up on day two. Anyone else test this and end up with a repair bill instead?

Nah man, you probably just did it wrong. Gotta use a microfibre cloth, not some random rag, and change it every 12 hours max. I ran that setup for a week straight in my own place and my electric bill dropped from $180 to $130 even with that heat wave we had. Sounds like your unit already had issues if it froze up that fast.

Oh man, that 30 percent claim was always way too good to be true.

Matched what I saw in the actual studies too.
